BRAKE BAND.

Application filed February 8, 1923. Serial No. 617,776.

To all whom it may concern:

Be it known that I, ALVIN H. SWEET, a citizen of the United-States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Brake Band, of which the following is a specification. Y My invention'relates to i brake bands, and particular y when they are housed or relatively inaccessible for relining. The objects of my improvement are, first, to provide a sectional lining that may be removed from, or'applied to, a brake band without disassembling or removing it from its normal position; and, second, to

afiord facilities for renewing only a portion of the lining and for re-arranging portions according to their relative condition of Other objects and advantages will appear hereinafter, and while I show herewith and will describe a preferred form otconstruction, I desire to be understood that I do not limit myself to. such preferred form, but

that various changes and adaptations may be made thereinwithout departing from the s irit of my invention as hereinafter c aimed.

These objects are attained by the construction illustrated in the accompanying draw in? in which-v i igure 1 is a perspective view of my armproved brake band, and Fi sectionav Similar numerals refer tosimilar parts The brake band strap 1 maybe of any usual and suitable form except that, where the width of end clips 2 is the same or nearly a nual to the width "of the strap, their inner w should be chamfered adjacent the stap. This is to expose the edges of the strap near its ends to afiord facilities for engagementby the lugs of the lining sec: tions. 7 V

The lining, previous to assembly, com- I prises a lurality of con led sections formed substantially as shown in Fig. 2. Of these the backers 3 are preferably made of sheet steel and have at one side an outwardly extending integral flanged lug 4, and at the other side an opposed integral projecting lug 5 in the plane of the backer. The length of lugs 5 is such that they may be bent to m rovements ine 2'is-a similar enlarged view of a palrof the lining the shape and dimensions of lugs 4. The backers have clinch points 6 pressed inwardly from the material of which they are formed, and friction material 7 is attached to the backers by means of these points as indicated in Fig. 1 at 8.

At their respective ends the backers are provided with (so-operative coupling means comprising tongues 9 and slots 10, so that .65

they may be hooked to ether to form a flexible continuously linked lining of the proper length prior to assembling in the brake strap.

Flanges on lugs 4 and 5 are often superfluous and may be omitted. In such cases, after assembling, the lugs" merely extend straight out from the hackers, and serve band, after assembling the lining sections into a continuous string, consists in slipping it into the strap axiallyand then bending lug's 5 outwardly around their edge of the) brake strap. In the case where lugs 4 are flanged they must of course be made to properly engage their edge of the strap prior to bending lugs 5. At the respective ends of the assembled lining the tongue 9 and slot-- ted end 10 are bent so asto hook around the ends of the brake strap in the manner indicated in Fig. 1. In a previous application filed July 27, 1922, Serial Number 577,935, which has matured into a Patent Number 1,460,118, June 26, 1923, and in companion applications filed. coincidently with this, I have shown some what similar brake band construction. None; of the said applications however claims what is claimed herein.

I claim: i

1. A brake lining comprising a plurality.

only to keep the sections in place so far as of linked sections, each having a radial lug 2. A brake lining comprising a plurality of linked sections, each having a radial lug adapted for engaging an edge of a brake strap by transverse sliding, and an opposed fiat projection adapted for being bent over the other edge of said strap for retaining the lining therein.

3. A brake lining comprising a plurality of linked sections, each having a radial lug adapted for engaging an edge. of a brake strap by transverse sliding, and an opposed fiat projection adapted for being bent over the other edge of said strap; the lug and I bent projection being adapted for maintain- 1 ing axial and radial relation between said lining and said strap.

4. In combination, a brake band; lining I comprising a plurality oflinked sections,

5. In combination, a brake band; a lining comprising a plurality of linked sections, each having a radial lug adapted for engaging an edge of said band and an opposed fiat projection adapted" for being bent over the other edge of said band; and means for retaining said lining in fixed circumferential relation to said band; the lug and bent projection being adapted for maintaining axial and radial relation between said lining and said band.
